GUIDE : Dreaded Chevron unlocker issue

For all of you trying to instal WP7 and getting stuck at the dreaded chevron unlocker "Uh-OH" that will not let you pass, look no further. There are a lots of ifs and buts but no definite answer to it. Below method worked 100%.
I tried it multiple times. I in no way encourage you to use WP7 and unlocking procedures but heres simply what you do if you want to do
Instal Zune
Connect WP7-HD2
Click on the sync relationship below the picture of your LEO70
key in any name...i used HD7
Once connected, create a zune id...You can use your windows live id though
Goto settings ---date and time and uncheck automatic date VERY IMPORTANT
sync your phone...Check if port 443 is free that means no SKYPE or anything. Instal registry key in windows
Put chevron installer on root of C
Stop any antivirus & anti spyware IMPORTANT
Run chevron with administrative controls
Make sure before running chevron that Wp7 is Screen on and not keypad locked. Make sure the white screen on zune is there clearly showing your phone model and name that you made.
I do NOT have the developers kit or tools installed.
I am on windows 7 64 bit
So this kills all speculations.
Hope you guys can get it to work.

I needed to disable my web proxy (Privoxy, in my case) for ChevronWP7 to work.
Note that you may need to reboot for proxy changes to be picked up by the Zune *service* (not the app).

also i had to close the SKYPE, however it sounds

can u make a video ?
i was traying last 2 day to sync my hd2 (w7) to my pc (windows 7) with zune software but nothing works

I have got WinXP SP3 and it's not working on that ever after using your method.

DID you disable the auto time settings?
did you add the registry key?
Mind restarting the phone and the PC?

I'm on XP to and i can't make chevron running. what do you mean about registry key? I have to add it on my computer?

Ok..some noob questions because every day i see new things here and to much info just confuse me... This guide will help me unlock (jailbreak) my phone without Activation from Microsoft?????
Or do i need to follow these instructions first following by the MS Activation:
http://forum.xda-developers.com/showthread.php?t=912218
Also...My only care is to sync Music and images on my WP7 HD2.. I don't need games and such! What do i need to do?? I am downloading zune right now...After that?????

There doesn't seem to be a cure-all for this issue.
I was able to get mine successfully unlocked yesterday almost by chance.
I had to keep going into Command Prompt (administrator mode), keying in c:/windows/system32/drivers/etc, and then executing "notepad hosts" and deleting the host file that the phone kept creating everytime I ran Chevron.
I also had my phone in airplane mode.
Today, I decided to blow up the phone with Task29 and reflash WP7 to see if it helped my battery performance. Much to my chagrin, I was unable to duplicate whatever worked for me yesterday.
I'm back on Android until this is fixed with a known, proven solution for multiple users.

i just install the windows phone drivres and it woks , i just unlock my hd2 but the market dosent work on the phone

how did you install the windows phone drivers because when I plug my phone on my computer ( windows Vista 32bit) it just say it just say installing that's it. Also i can't see the phone in Zune no matter what USB port i use or computer. Help would be greatly appreciated.

So to get this straight...to sync my images,music (ONLY!!!) I have to Activate my Phone with Microsoft??

[Best Solution] ChevronUnlocker connection issue.

Drakosha said:
Hello to all!
I think, I've finally found the reason why Chevron almost never works. After a few days of struggle, I managed to successfully unlock my HD2 three times in a row, all by the same trick.
The idea is to change the IP which Chevron emulates DURING the process of jailbreak. Here's step-by-step.
1 - Disable LAN card in your PC (Control Panel\Network and Internet\Network Connections\ right click on "Local Area Connection" and choose "disable"). It is very important to disable ALL connections, but you MUST remember which one is used for Internet access (see below, why).
2 - Do all the standard steps of unlock - install certificate, start WPConnect e.t.s. When Chevron fails to unlock - LEAVE IT OPEN.
3. Start Notepad and open hosts. Delete lines added by Chevron (at the bottom). Save. LEAVE NOTEPAD OPEN.
4. Press Win+R and enter IPConfig /flushdns , press "enter". CMD window will blink for a second - that's normal.
5. Press Win+R again (there will be IPConfig /flushdns typed already), but DO NOT PRESS "ENTER", just leave this window open.
6. Now the trick. Start WPConnect. WHILE it connects, continue to repeatedly press "Unlock" button in Chevron, until the black CMD window of WPconnect disappears. Chevron will fail to do its job, but that's in fact is the very thing we need.
7. Now, do not touch Chevron window, just return to Network Connections and ENABLE yor LAN card.
8. Go to Notepad and JUST CLICK "Save", do not alter anything inside.
9. Return to the window with the typed command IPConfig /flushdns . Press Enter.
10. Start WPConnect, WAIT until it disappears, and press "Unlock" button in Chevron. You're done - this time unlock would work.
At least, it worked for me 3 times in a row, while NO other ways worked.
Best regards - Draco.
P.S. If you have firewall - disable it before doing anything.
P.P.S. Win7 from NAND + MDJ Desire HD 4.4 from SD = best phone in the world

I have followed other guides posted here before, but none is as reliable as this one. Flawless. (Note that Zune is not required at all during this process, WPConnect is used)
Extra precautions :
1) Make sure port 443 is not used. You can open command prompt and type netstat -aon. From there, check which ip ends with 443 and check its PID number.
Once you have acquired the PID, go to command prompt and type tskill <PID number>.
2) Close skype.
3) Turn off your antivirus / firewall.
4) Make sure that during executing WPconnect.exe you're phone should NOT in be in sleep-mode/locked.
5) Make sure your host file located in C:\Windows\system32\drivers\etc\ is not read-only.

WPconnect is an executable used to connect your PC to wp7 devices without having to open ZUNE.
You can find out more about it here http://forum.xda-developers.com/showthread.php?p=10609273#post10609273

I test all solution, why not these one? I will reflash WP7 and test
Thanks for the TIP !

Ok.. now I know.. but the major problem is that I have Windows Xp.. so no chance to try tha trick... :-(

As I click on WPConnect.exe it just blinks for 1 second an closes then. What am I doing wrong?!

Can you read what is says in the window before it closes? Usually WPconnect just opens for 2-3 seconds and after a connection is established it will close back. If it says "Connection is established" or something like that, means you're good to go.
Read the steps carefully.

Ahah, i remove WP7 from my device but i test WPConnect, got the same problem... So i made a quickscreenshot, to see the error message, this is it !!

or this one!

yeah, that's just the same as I get when running WPConnect.

Yes but does it solve your problem?
I post 2 screenshot;
-Compltly close Zune
-Connect the device

Here's what i did, connect the phone to PC via USB, let zune opens and sync. Then close zune. Rune WPconnect.exe. It should say "Trying to establish a connection with blablabal" then "Connection established" and it will close. Try that.

You mean you dont have WP7 on your HD2 and you try WPconnect with it? That wont work. Anyways also make sure you're not in sleep mode or lock mode when you use wpconnect.

Hum, only (no lock--> set to never..)
I did, step by step what |OP| Posted !

I got so excited when I found this particular thread. Of all the hacks and mods for Chevron out there this one seemed to be the most realistic solution. I have to XP machines. I managed to install Windows Phone Development Tools on one(everything works except emulator and debuger) I downloaded the WPDTOctober2010Update_en.msp, and insured it installed to C:\Program Files\Microsoft SDK's\Windows Phone\v7.0\Tools\WPConnect.exe.(REBOOTED)
After I set up my HD2(again) Followed all the sugested settings, and downloaded Chevron cert via WIFI email. I began the steps on the 1st post.
1) I disabled all connections
2) I plugged in phone and through file explorer double clicked on WPConnect.exe and I got this error
" C:\Program Files\Microsoft SDK's\Windows Phone\v7.0\Tools\WPConnect.exe is not a valid Win32 application."
I bet if I had WINDOWS 7 this would not be the case. Any help, advise solutions would be appreciated. Thanks.

Also people have tried to help you, Yu are obviously doing something wrong or there is something on your pc that is blocking your connection, try and read some guides and disable anything that could potentially be blocking it.

OK start up your mobile. Is the date and time correct (Very important) if all ok then start zune. open up the chevron on c/drive and see if it will connect with ot the Ohno message.
You may have to do this a few times. try the other computer as well.
Some guy's can get the chevron to work, by puting the date a few months forward NOT back.
If you do manage to get the chevron unlocked, then dont lock it.
Make sure to swith off spyware detectors, and put your antivirus into stand by mode until you complete this tasks.

Two things to try out...
1. Turn UAC off... It could be that it might be asking for Admin rights but stays stuck for some reason..
or
2. Try the install again but disconnect from the Internet like that it cant check/download for an update
Maybe antivirus software could be doing something wrong... So turn it off and see

what is UAC???
i believe when i uninstall the ZUne software.. there are still some remaining zune things inside... that why i struck in installation part...
i even try to install it in the SAVE MODE... also struck....

1. Download the zune package thru Microsoft.com [save it on your desktop] [one from microsoft]
http://www.microsoft.com/downloads/en/details.aspx?FamilyID=ab1a80ed-e337-4346-9d5a-f00cfb467514
2. Open the "Run" program by hitting "Start" typing "RUN" under start search and hit "Enter" key [or just press and hold "Windows key" + "R"]
3. A small window on the lower left of your screen should show up
4. Then, "Drag and Drop" the "ZunePackage47.exe" [file downloaded from mircosoft.com] towards the box on the "Run" program
[simply hold the left click on the "ZunePackage47.exe" then move you mouse towards the "Run" program then release the left click]
"if its successful you should have thepath/location of the file on the 'Run' program"
5. Then on the"Run" program, go to the very last part of the path after".exe" then add" " [space] followed by"/x"
it should show something like: "C:\[path or location of file]\ZunePackage47.exe /x"then click"OK"
6. Just follow the prompt messages and it will extract additional files and folders to you desktop
7. Afterwards go the folder [x86 orx64 (depends on you Operating System Type)] then access folder with a name "packages" and try to run the file "zune-x64" or "zune-x86" and if you recieve any error message just continue installing it. It should still install

i still have trouble installing this zune software >.<!
i guess i just go for an android os...

Dell Venue Pro..I think I have a demo model

I got a Venue Pro yesterday. I purchased it on eBay. Hooked it up to perform updates and I couldn't. I constantly get error code 80070002
I have tried it now on two PCs on two different networks, one running Win 7 and the other running Win 8. I have looked on the net but can't really find anything helpful.
Anyway, never having had the phone before I found it odd that it came with a call and message history. Even after I reset the phone it still has a history, pictures of people from Facebook with pictures that are obviously professional shots. All messages are from people each other how great their new Windows phone is.
Also, if I don't use the phone for a couple of minutes it starts a phone demo video/slide show. I am now thinking I have a demo OS even though I can make calls and surf the net. Current OS is 7.0.7004.0
What can I do to totally wipe this phone and start from blank?
Thanks

You'll probably have to follow the instructions in "How to unbrick a Dell Venue Pro." No way to change a demo ROM into a retail ROM. You need to flash the retail ROM and start over.

If you still have the original rom installed on it, could you:
run the emapp tool and write down the contents of what it has?
As far as dell is concerned, I dont believe they normally make demo specific roms.
But that is in reference to their android devices and MS might have had them make an exception for the VP (and it's WP7)

Hi, I just got a phone in the same conditions you have had mention(demo mode), and I thought I have done and taken the same steps to flash my device, but with not avail, the skydrive file has been removed, and I was wondering if you maybe still have them(the files) somewhere and if I could "borrow" them. I mean I think I have the right ROM and the UpgardeWp, but maybe they are the wrong ones, because is NOT working for me.
Thank you very much and I hope you have a fantastic evening.

*UPDATE* never mind, I was able to do a proper flash, and now I have a good working Windows Phone...

Hi
I am trying to do the same thing. But when I click the sky drive link to download the rom , there is nothing there. It asks me to login to windows live and thats it. Do you still have this rom downloaded and can you email it to me? OR where can I find this rom? Plz help.

In the middle of the "how to unbrick your dell venue pro" the rom is posted, on some russian download site.
http://forum.xda-developers.com/showpost.php?p=22415484&postcount=35
That file is hosted on my skydrive, and it is still available. It may be asking you to log in to your windows live account to access it. Not sure.

I got it ! Thank you so much!!!!!!!!!!!!!!!!!!!!!!!!!!!!

First thing I'd do is do a soft reset if you just flashed the stock 7004 ROM.
Windows Phone > Settings > About > Reset your phone.
Then, just a guess -- go into Zune Desktop > Settings > Phone > Sync Options > [Forget this phone]
Then plug the phone again and see if it lets you set it up as a new device, with update check.
If this doesn't work, the next thing I'd try is moving to another Windows machine, installing a fresh copy of Zune Desktop, and seeing if it will let you update using that. You could also use a Windows installation in virtualization using virtualbox, or an installation on another partition if you are an advanced user.
Basic troubleshooting. Just floating ideas.

Nothing worked

If you've also tried doing the soft reset as I mentioned, you may want to see if you can use the cab sender method to update to one of the nodo builds.

A couple quick questions --
Was this your phone and had it been working previously, or was it in this "connect to PC screen" state when you got it?
Can you think of anything you might have done to cause it to stop working?
Is it the AT&T, T-Mobile, or EU/International version?
Did you use a non-english language cab?

1. yes, i tried a soft reset(resetting the phone from settings->about phone->reset phone) even also perform a soft reset without SD card and try to update from zune without SD card but still getting same restoration error.
i already tried all options cab sender, mangoforall 0.2 etc/ update and restore from command promt:
getting below error everytime whenever i tried to perform any thing from command promt(.bat) :
Error: Exception from HRESULT: 0x801812C0
Call stack:
at wm7update.Program.UpdateDevice(IDeviceInfo deviceInfo, List`1 updates, Upd
ateType type)
at wm7update.Program.Main(String[] args)
2. this is not my phone i got it in a non working state showing "SD card not working".. then i performed steps mentioned in "how to unbrick DVP". after that i got a working DVP.
3. It is a T-mobile DVP and sim unlock by unlock code provided by dell.
4. It is on 7004 Tmobile ffu no cab update til now, as i am not able to send any cab via cab sender.
Note: i don't have any previous back-up of this mobile and not sure wheather the SD card is original or not.
